A new research paper published on arXiv explores the critical issue of validation practices in machine learning models for predicting ship fuel consumption. The study highlights that traditional random train-test splits can lead to overly optimistic performance estimates due to temporal data leakage. By employing time-aware evaluation methods like Time Series Cross-Validation (TSCV) and Blocked TSCV (BTSCV) on operational data from the Canadian Coast Guard Ship (CCGS) Sir Wilfrid Laurier, the research demonstrates a more realistic assessment of model performance.
